Uyini umehluko phakathi kwe-RGB ne-CMYK yephrinta ye-Inkjet?
Imodeli yombala we-RGB isho imibala emithathu eyinhloko yokukhanya: Okubomvu, Okuhlaza, Nokuluhlaza okwesibhakabhaka, ukukhanya kombala okuthathu okunezilinganiso ezihlukene zesamba, kungakhiqiza ukukhanya okuhlukahlukene kombala, ngokombono, okubomvu, okuluhlaza okotshani, okuluhlaza okwesibhakabhaka kungaba ixutshwe kuyo yonke imibala.
Ku-KCMY, i-CMY ifushane ngokusho okuphuzi, okusasibhakabhaka, kanye ne-magenta. Lena imibala emaphakathi ye-RGB (imibala emithathu eyinhloko yokukhanya) exutshwe ngababili, okuwumbala ohambisanayo we-RGB
Ngaphambi kokungena emininingwaneni, ake sibheke lokhu okulandelayo:
Esithombeni, singabona ngokucacile ukuthi umbala we-pigment we-CMY uwukuxuba okukhiphayo, okuwumehluko obalulekile, kungani-ke umshini wethu wesithombe nephrinta ye-UV kuyi-KCMY?Lokhu kungenxa yokuthi izinga lamanje lobuchwepheshe alikwazi ukukhiqiza ukuhlanzeka okuphezulu ngokuphelele i-pigments, i-tricolor mix ngokuvamile akuyona emnyama evamile, kodwa umbala obomvu obumnyama, oyinki okhethekile omnyama u-K ukuze unciphise.
Uma sikhuluma ngokwethiyori, i-RGB empeleni ingumbala emvelweni, okuwumbala wazo zonke izinto zemvelo esizibona ngamehlo ethu.
Embonini yesimanje, amanani ombala we-RGB asetshenziswa esikrinini futhi ahlukaniswa njengemibala ekhanyayo. Lokhu kungase kube ngenxa yokuthi ukuhlanzeka kombala kokukhanya kuphakeme kakhulu, ngakho umbala obonisa kangcono amanani ombala we-RGB.Ngakho singakwazi futhi ukuhlukanisa yonke imibala ebonakalayo njengamavelu emibala ye-RGB.
Ngokuphambene, imibala emine ye-KCMY iyiphethini yombala enikelwe ekunyatheliseni kwezimboni futhi ayikhanyi.Inqobo nje uma umbala uphrintwa emithonjeni ehlukahlukene ngemishini yokunyathelisa yesimanje, imodi yombala ingahlukaniswa njengemodi ye-KCMY.
Manje ake sibheke ukuqhathanisa phakathi kwemodi yombala we-RGB nemodi yombala ye-KCMY ku-photoshop:
(imvamisa, ukwakheka kwezithombe kuzoqhathanisa umehluko phakathi kwemibala emibili yokuphrinta kwe-rip)
I-Photoshop imise izindlela ezinemibala emibili i-RGB ne-KCMY ukuze yenze umehluko.Eqinisweni, umehluko awumkhulu ngemva kokuphrintwa, kodwa uma isithombe se-deal ku-RIP enemodeli ye-RGB, uzobona umphumela wokuphrinta umehluko omkhulu uma uqhathanisa nesithombe sokuqala.
